A leading international architectural practice has installed eco-cistem™ at its headquarters in London.

eco-cistem™ Director, Graham Kelly, said: “This international architect has an unquestionable pedigree designing some of the world’s greenest buildings.

“By installing eco-cistem™ in its headquarters, a huge amount of water will be saved every year.

“Data from a recent office installation showed eco-cistem™ reduced the amount of water used to flush the toilet by over 75 per cent.

“And for the first time for a cistern, architects could claim two extra BREEAM credits and as many as five when eco-cistem™ is used with other water saving devices.

“Up to six LEED points could also be achieved.”

eco-cistem™ is the world’s only cistern to use condensate from air conditioning units to flush the toilet.

In doing so it virtually eliminates the need to use mains water.
